Wasp 1: Huntsman spider 0

An epic journey played out on the basketball courts last week during sport. Having mastered his prey this valiant wasp dragged the much bigger huntsman spider across the full length of the basketball court to the relative safety of his (or her) hidey hole in a crack in the steps. This demonstration of the food web in action both concerned and fascinated students in my sports group. As well as protecting students from the wasp and vice versa I managed to video a small part of this epic journey.

Invisible Black?

Excerpt from SMH article: The nanotube material, named Vantablack, absorbs all but 0.035 per cent of visual light – a new record according to the British scientists who created it.

Made of carbon nanotubes each 10,000-times thinner than a human hair, the blacker-than-black material is produced on sheets of aluminium foil. When crumpled, the uneven surfaces covered with the material become indistinguishable.

“It’s like black, like a hole, like there’s nothing there,” Surrey NanoSystems chief technical officer Ben Jensen told The Independent.

Year 11 2013 Subject Selection

Our current Year 10 students are selecting subjects for their senior studies in 2013 – 2014. This is often a daunting task.
Below is a link to a University of Sydney resource that provides information concerning a range of science related careers, including plausible employers and salary ranges.
This is not meant as a specific endorsement of the University of Sydney, rather providing access to a helpful resource.
